Introduction: Ways of Machine Seeing
How do machines, and, in particular, computational technologies, change the way we see the world? This special issue brings together researchers from a wide range of disciplines to explore the entanglement of machines and their ways of seeing from new critical perspectives.

Prove All Things and Holf Fast That Which Is Good: The Missouri Supreme Court Redraws the Line between Plain Error and Ineffective Assistance of Counsel - Deck v. State
Few challenges to a judicial determination are as disruptive as a criminal defendant’s allegation of ineffective assistance of counsel. Discovering the truth behind such an allegation is extremely difficult, owing both to the distorting effect of hindsight and the near impossibility of discovering the full extent of any damage caused by defense counsel’s alleged errors. This Note examines the genesis of the confusion concerning the current standard for granting post-conviction relief due to ineffective assistance of counsel and the Missouri Supreme Court’s most recent effort to clarify that standard in Deck v. State

Brand gender and consumer-based brand equity on Facebook: The mediating role of consumer-brand engagement and brand love
Brand gender has been suggested as a relevant source of consumer-based brand equity (CBBE). The purpose of this paper is to deepen understanding of the relationship between brand gender and CBBE by analyzing the mediating roleofconsumer–brandengagement (CBE)andbrandlove(BL)onthisrelationship.Thisresearchwas conducted on Facebook, the dominant global social media platform. The hypotheses were tested using structural equation modeling. Results support 6 of the 9 hypotheses, with a significant relationship between analyzed constructs. This study advances prior work by showing that brand gender has an indirect and relevant impact on CBBE through BL and CBE. Therefore, this research confirms the advantages of clear gender positioning and extends prior research by suggesting that brands with a strong gender identity will encourage BL and CB
The VCG Mechanism for Bayesian Scheduling
We study the problem of scheduling m tasks to n selfish, unrelated machines in order to minimize the makespan, in which the execution times are independent random variables, identical across machines. We show that the VCG mechanism, which myopically allocates each task to its best machine, achieves an approximation ratio of O(ln n&frac; ln ln n). This improves significantly on the previously best known bound of O(m/n) for prior-independent mechanisms, given by Chawla et al. [7] under the additional assumption of Monotone Hazard Rate (MHR) distributions. Although we demonstrate that this is tight in general, if we do maintain the MHR assumption, then we get improved, (small) constant bounds for m ≥ n ln n i.i.d. tasks. We also identify a sufficient condition on the distribution that yields a constant approximation ratio regardless of the number of tasks
RNA-Seq identifies genes whose proteins are upregulated during syncytia development in murine C2C12 myoblasts and human BeWo trophoblasts
The fusion of villous cytotrophoblasts into the multinucleated syncytiotrophoblast is critical for the essential functions of the mammalian placenta. Using RNA-Seq gene expression, quantitative protein expression, and siRNA knockdown we identified genes and their cognate proteins which are similarly upregulated in two cellular models of mammalian syncytia development (human BeWo cytotrophoblast to syncytiotrophoblast and murine C2C12 myoblast to myotube). These include DYSF, PDE4DIP, SPIRE2, NDRG1, PLEC, GPR146, HSPB8, DHCR7, and HDAC5. These findings provide avenues for further understanding of the mechanisms underlying mammalian placental syncytiotrophoblast development
Resource augmentation in load balancing
We consider load-balancing in the following setting. The on-line algorithm is allowed to use machines, whereas the optimal off-line algorithm is limited to machines, for some fixed . We show that while the greedy algorithm has a competitive ratio which decays linearly in the inverse of , the best on-line algorithm has a ratio which decays exponentially in . Specifically, we give an algorithm with competitive ratio of 1+2^{- frac{n{m (1- o (1)), and a lower bound of 1+ e^{ - frac{n{m (1+ o(1)) on the competitive ratio of any randomized algorithm. We also consider the preemptive case. We show an on-line algorithm with a competitive ratio of 1+ e^{ - frac{n{m (1+ o(1)). We show that the algorithm is optimal by proving a matching lower bound. We also consider the non-preemptive model with temporary tasks. We prove that for , the greedy algorithm is optimal. (It is not optimal for permanent tasks.
Phase Steering and Focusing Behavior of Ultrasound in Cementitious Materials
Deterioration of civil infrastructure system (CIS) raises not only safety issues but also socio-economic concerns. In order to meet the high demand of structural condition assessment and health monitoring, development of quick, reliable and accurate NDE methods became critical issues recently. Compared to metal structures, NDE for cement-based materials is still premature and requires further development
Analyzing consumer-based brand equity on Facebook: the impact of brand gender
In recent years, Facebook and other social media have become key players in branding activities. However, empirical research is still needed about the way in which consumer-based brand equity is created on social media. The purpose of this paper is to study the relationship between masculine and feminine brand personality and brand equity, on Facebook, and to analyze the mediating role of consumer-brand engagement and brand love on this relationship. Data were collected using an online survey with 614 valid responses. The hypotheses were tested using structural equation modeling. Results support 7 of the 11 hypotheses with significant relationship between analyzed constructs. This study confirms the advantages of a clear gender positioning and extends prior research by suggesting that brands with a strong brand gender identity will encourage brand love. Results also highlight that brand love has a mediating role on the relationship between brand gender and overall brand equity
